While re-configuring the PC's liquid cooling loop as explained below, I discovered that the CPU waterblock (EK Supremacy EVO CPU Water Block Nickel) had a crack on its output port. This is the 2nd CPU waterblock that I had cracked. The crack on the first was a lot deeper and had propagated to near failure after about 6 months. Thankfully I discovered that before it failed. I then replaced with an identical model while liquid cooling the GPUs in late 2017.
I was distraught to find that the new one had also cracked. This time, the cracks around the output port were so fine that the connector blocked it, and thus was only visible when I removed the tube to work on the new loop. Due to this, I ordered the 3rd one (this time the EK Supremacy EVO CPU Water Block Gold). The new Gold version costs only £15 more than the previous 2 Nickel ones.
This was my project in early May 2018. The objectives of this project were:
1) Replace the existing "EK-XTOP DDC 3.2 PWM Elite - Plexi (incl. pump)" & "EK-DBAY Spin Reservoir (R3.0)" with the 2-in-1 "EK-XRES 140 Revo D5 PWM RGB Reservoir Pump Combo".
2) Replace the top mounted "EK-CoolStream XE 360 (Triple)" radiator with the thinner "EK-CoolStream PE 360 (Triple)"
The reasons behind these were:
1) The previous 5.25" bay mounted "EK-DBAY Spin Reservoir" made A LOT of noise due to water falling down into the pool from the top. This is was the only noise I heard while playing games or watching movies. The brain tunes it out, but it was still an unnecessary annoyance. Since I had spent so much money on the PC, I wanted to get it right sooner rather than later. The new reservoir has the input port located below the water line and is thus almost silent in operation.
2) The previous "EK-CoolStream XE 360 (Triple)" was incompatible with this "Corsair Obsidian 750D" casing when used with the "Asus ROG Maximus IX Formula" motherboard. The motherboard's own water block interfers with one of the fan mounting positions and thus the XE 360 radiator could only be used with 2 instead of 3 fans. Using the thinner PE 360 solved this problem.
This was to action the above.
In the process of doing so, I discoverd an unfortunate crack on the previous "EK-FC Terminal DUAL Serial 3-Slot - Plexi" SLI terminal block, and had to replace this with the new "EK-FC Terminal X2 S 3-slot - Plexi". This required an additional EK-AF fitting as the new model lacks a side G1/4 port.
This PC is cooled exclusively by EKWB (Edvard König Water Blocks) parts. The coolant used was EK Water Blocks EK-Ekoolant Pastel RED (concentrate 250mL) mixed with 750mL of de-ionised water from CarPlan.
As can be seen in the video, I had shorted the ATX connector to turn the PSU on. I'd also disconnected the ATX CPU power supply cable from the motherboard just to be safe.
EKWB is the world's leading PC water and liquid N2 cooling specialist. The company only offers these solutions, unlike the other brands that are basically just product lines of a much wider product catalog.
